To aZ-Z 'whom t may concern. j

Be it known ythat l, SOMA HERZOG, a citizen of the United Stat-es, andresident of the borough ot Manhattan, city, county, and State of ,NewYork, have invented certain new and useful Improvements in Chairs, ofwhich the following` is a specification.

My invention relates to chairs and has for its object to provide aconvertible chair of simple and improved construction and arangement.Other more specilic objects of my invention will appear from thedescription and the features of novelty will be pointed out in theappended claim.

Reference is to be had to the accompanying drawings, which, torillustrative and descriptive purposes, show two forms ot my inventionand in which Figure 1' is a perspective view of one form of my improvedchair; Fig. 2 is a central vertical section thereof; Fig. 3 is a similarview showing said chairconverted 'for use as a step-ladder; Fig. 4 is arear view; Fig. 5 is a side elevation showing another form of myimproved chair; Fig. 6 is a rear view thereof and Fig. 7 is an elevationshowing said chair converted into a wheel-barrow or the like.

As shown` in the drawings the4 chair comprises a seat 10 and` irontsupporting members or legs 11 rigidly secured thereto; in order toincrease the rigidity of the construction the customary rungs or crosspieces 12 may `be provide-d between said front members in thewell knownway. Rear members or legs 13 are pivotally connected to the seat 10 at14. and are continued upwardly beyond the same as'shown, for instance,in Figs. 1 and, the members 13 being connected by means oirungs or thelike 145 locatedat spaced intervals throughout the length of said rearmembers13. rllhe rangs 15 may be of rectangular cross section as inFigs. 2 and 3 or they may be ot circular cross section as in Figs. 5, 6and 7, it being understood that in some cases said rungs be oit stillother cross sectional terms.

' In both oi2 theillustrated forms ot my chair the rear members 13 andrangs 15 togetherjtorm a rear trame which is capable ot pivotal`movements relatively to the seat 10 about the pivots 14. ln each casethe seat 10 or some other appropriate portion of the chair is providedwith one or more inclined shoulders 1G and vertical shoulders 16aLarrangedin the pivotalpaths of the rear members 13 and adapted toengagethe same to arrest the pivotal movement ot said rear yshown iixedand steadied thereby in said inclined position. ln the `form shown inFigs. 5 to 7 inclusive the rear frame is pivotally movable in theopposite direction to the posit-ion shown in Fig. 7 in which theshoulders 16 engage the rear members 13 to securely brace the same inthe inclined position indicated. ln both forms the vertical shoulders1GEL engage the rear members 13 and brace the same in their normalupright positions.

Referring now more particularly to the term shown in Figs. 1 to 4 thechair includes a panel 17 pi-voted at 18 between the rear members 13near the upper ends thereot. llhen the chair is in the normal conditionshown in Fig. 1 this panel 17 may depend from the pivots 18 between themembers 13 to form the back of the chair.; or said panel 17 may be swungto the horizontal position shown in Fig. 2 in which it rests, forinstance, upon the uppermost rung 15 and projects rearwardly from thechair. In this condition the panel may be used as an invalids table toextend over a bed or as a table to be used by a person straddling thechair. rEhe panel 17 may also' be brought to the position shown by `fullllines in Fig. 3 in which its tree end` rests upon the seat 10; in thisposition the panel forms a brace whereby the rigidity or the'rear framein its inclined position is increased. To prevent slipping ot the panelupon said seat 10 a latch 19'may be slidably carried by said panel,saidr latch, in its operative position extending into notch 2Ov formedin the chair seat 10. ln addition to the above the panel. 17 may beadjusted to the position by dotted lines in Fig. 3 in which it serves asa shelf whenthe rear trame occupies the inclined position shown. Thepanel 17 may be maintained in the indicated dotted position in anysuitable manner as by means of lugs 2l pivoted to the panel andextending beneath the upper rungs 15 in their operative positions.'llhelatch 19 and the lugs 21 are all movable to inoperative positionsin which ythey lie entirely within the panel 17 when not required.

This form of chair includes further a brace comprising members 22pivotally connected at 23 to the front supporting members 11 and havinghooks 24 and a projection 25 adapted to coperate with a cross bar 26extending between and connected with the rear members 13. The cross bar26 is preferably provided with recesses 27 for the accommodation of themembers 22 when the hooks 24 are used and with a notch 28 for coperationwith the projection 25 when the latter is used.

When the rear frame is in its normal condition as shown in Figs. 1 and 2the hooks 24 lie behind the bar 26 and thus maintain the rear members 13in contact with the shoulders 16a and against pivotal movement. `When intheinclined position shown in Fig. 3 the shoulder 25 lies behind the bar26 in registry with the notch 28 thereof whereby the brace 22 holds therear members 13 rigidly in their inclined positions against the inclinedshoulders 16.

In the form shown more particularly in Figs. 5, 6 and 7, the chairincludes also a panel 17a pivoted at 18a between the rear members 13 andin its normal position depending from said pivot 18a between saidmembers 13 to form the back of the chair as shown in Fig. 5. The panel17EL is adjustable to a horizontal rearwardly eXtending positionindicated by the dotted lines a in Fig. 5; in this position said panelmay be used as a table in the same way as indicated with respect to theform shown in Fig. 2. In the form being described the panel 17il ismaintained in the position a by means of a lug 29 projecting outwardlyfrom the upper rung 15av which in this case is rotatably mounted betweenthe rear members 13. A pair of members 30 are connected with the rung15a and project therefrom in directions opposite to that in which thelug 29 extends; these members 30 by their weight normally maintain therung 15a in a position in which the lu@` 29 extends upwardly to form arest fbr the panel 17a when it occupies the dotted position a. Byswinging the members 30 rearwardly the lug 29 is removed from beneaththe panel 17a which is thus released and may assume the inclinedposition indicated by the dotted lines 5 in Fig. 5. In this position thelug 29 and members 30 extend lengthwise beneath the panel 17a andprovide a rest whereby the panel is maintained iii the inclined position5,' when thus adjusted the panel 17a may be used as an easel or as ablackboard, in which case the one surface thereof may be covered withsilicate or otherwise treated to provide a writing surface which may beY yreadily cleaned.

The form at present being described includes also a wheel 31 carried bythe lower rung 15b which is also rotatably mounted between the rearmembers 13; in the normal position of the chair this wheel 31 does notcontact with the surface upon which the chair stands as shown in Fig. 5.By adjusting the rear members 13 to the inclined position shown in Fig.7 and by swinging the members 30 outwardly beyond said rear members 13as shown in said figure, the members 30 may constitute handles wherebythe chair in this condition may be trundled land cooperating pins 36which prevent the joints from breaking downwardly and permit said jointsto break upwardly without interference when the rear members 13 areadjusted to the position shown in Fig. 7. rIlhe braces, in their normalpositions shown in Fig. 5, lock the rear fraine or rear ineinbers 13 intheir normal upright positions against pivotal movement.

Both forms of my chair are simple in construction and may be easilyconverted to serve different purposes. For instance, the chair in Fig. 3becomes an eflicient step ladder while the chair in Fig. 7 becomes awheel conveyance from which a child may derive amusement as a toy orwhich may be practicall7 used for conveying purposes.

I arious changes in the specific forms shown and described may be madewithin the scope of the claim without departing from the spirit of myinvention.

I claim:

A convertible chair comprising a seat, front legs rigidly connectedtherewith, a rear frame pivotally connected with said seat and extendingbelow thesame to form rear legs and above the saine to form back posts,a panel freely pivoted between the latter out of engagement with saidseat to constitute in its normal position, the back of the chair,V

said panel being movable into engagement with said seat to prop saidrear frame in an inclined position relatively to said seat and beingmovable to a horizontal position extending rearwardly of said rear frameto form a table and means on said seat coperating with said rear frameto determine its normal upright position and its inclined position withrespect to said seat.

In testimony whereof I have hereunto set i my hand.

SOMA HERZOG.
